-
-The <b>wx.MimeTypesManager</b> class allows the application to retrieve the
-information about all known MIME types from a system-specific location and the
-filename extensions to the MIME types and vice versa. After initialization the
-methods <b>GetFileTypeFromMimeType()</b> and <b>GetFileTypeFromExtension()</b>
-may be called: they will return a <b>wx.FileType</b> object which may be further
-queried for file description, icon and other attributes.
-
-A global instance of <b>wx.MimeTypesManager</b> is always available as
-<b>wx.TheMimeTypesManager</b>. It is recommended to use this instance instead
-of creating your own because gathering MIME information may take quite a long
-on Unix systems.
-
-This demo shows how to use wx.TheMimeTypesManager to list all known MIME types
-and retrieve that information as a wx.FileType from either an extension or
-MIME type.
-
-For further information please consult the wxWindows documentation for
-<b>wx.MimeTypesManager</b> and <b>wx.FileType</b>.
